Oddly enough, it seems my mkiii's SD card reader just died overnight. No matter what card I put in, it won't be recognized. This is not one of those "cannot format card" type failures, the camera doesn't see any sd card period. CF works fine, but recently I had a good deal on some nice 8gb cards, so I have 48gb worth of them. Anyone have any ideas/similar experience?
And yes, tried resetting the camera.
